I am getting my R32 back next week. I have had an RB25DET series 1 motor, and gearbox fitted. It also has a short shifter, Apexi AVC-R, heavy duty clutch, front mount, and full 3 inch exhaust with high flow cat.

Any ideas of what I can expect in terms of kw.

Boost levels are still not decided on for the AVC-R, going to have her properly tuned on a dyno, and go with the tuners suggestion.

Please keep in mind that this will be a daily driver - so boost will not be above 12psi..

If you can spend the coin then its the way to go. I havent been in dozens of modded cars, but i have been in a few, and my fav is a friends old R33/RB25 with a 2530. As a street car it was awesome, 230odd rwkws and the thing was mega responsive:thumbsup:

Im making almost that power with my RB20 but its just not the same:(

Ive got a series 1 R33 and have the same mods that you have listed.

My car just got dyno tuned and has put out 180rwkws but thats with a SAFC2 on 8.5 psi.

So if ya willing to up da boost a little more then i would say you would get bout 190rwkws and then you will be limited by your turbo coz they cant handle any more than 11 psi reliably anyway.

There was nothing wrong with the RB20. I just went in my friends RB25 R32 a few years ago, and was very impressed.

I bought the R32 very cheap to begin with, so I went for it. Just a big improvement over the RB20DET with sensible everyday driver mods.

GTST - no you can't steal the parts off it as the RB20 was sold today.

I will advise the cost when I get the final bill - hopefully it won't be a bank account tsunami.

I put a RB25DET series 2 motor, into my R32 12 months ago. At the time it was running stock boost, and achieved 155 rwkw (a good step up from 94rwkw).

You power figure will depend on how much boost you want to run. The thing that I love about the new engine, is the response of the series 2 turbo - I'm at 9psi boost by 2500rpm.

      Is the panel filter one that is oiled? Have you ever cleaned or touched the AFM?

      So.... the K&N air box thingo was too big, ended up gifting it to a mate, well, by gifting it he actually supplied food and beer at the pub,  which was nice, as it will not sit on a shelf in the garage for the next 10 years I did trim up some of the existing stuff to neaten it all up and gave it some wrinkle paint, unfortunately it currently has a used and abused mish mash of different types of hose clamps, 4 big fat T bolt type (shit), and a few normal clamps of vairing sizes and brands, but..... only until the 6 constant tension black worm clamps that I ordered from EFI solutions turn up next week Currently the current hose clamps are triggering me hard, LOL Is this the final version, probably not, I really want just 2 silicone pieces, a straight bit of silicone from the filter to the MAF is easy and will happen as soon as I head into Just Jap tomorrow, the problematic part is a 30° silicone bend from the MAF to the TB that I can connect the engine breather from the head, I found that there are bulk head fittings for boat bilge pumps that should work, but until I can get a 30° silicone bend the alloy pipe, and the 11ty thousand hose clamps, are there for the foreseeable future 4 hose clamps are golden, 6 are grudgingly acceptable, the 8 currently holding it all together is just taking the piss    I've also ordered 60 more retaining wall blocks for the front yard, I mis-gonculated the height that was required to get above the base of the Photinia's (red robin's) that are the hedge behind the front fence, currently it is 2 blocks high, and about 1/2 a block short, so going 3 blocks high will be above the base of the red robin's, and allow some room for mulch

      It is the stock air box with the panel filter. Everything else is stock except the exhaust at this point, as I also went back to the cleaned 270cc injectors. I will check the RPM when the IACV is unplugged and report back.

      As MBS suggested if this is happening when the engine is cold you're going to want to remove the intake air regulator and verify resistance + that the shutter is physically opening and closing. At -20C should be fully open, 20C half open, over 60C fully closed. At 20C should be 70-80 ohms. For AAC valve testing using a Consult cable see if you can raise and lower the idle by commanding more or less AAC duty cycle. Hopefully it's pretty linear as well, shouldn't be like 30% AAC valve is barely idling and 40% is 1500 rpm.
